The 27-year-old London-born model - who is in a long-term relationship with pop star Pixie Lott - said that he is 'very proud' to be part of the campaign while the range is 'looking so sharp and taking on a new direction'.

Ahead of the launch, dapper-looking Oliver shared his sartorial secrets with FEMAIL and revealed the key to looking good is to 'understand your body shape'.

Having modelled for M&S Menswear for the past two years, Oliver - who is signed to the same agency as David Gandy and Agyness Deyn - was the perfect ambassador for the line, which combines formal wear and casual sports luxe pieces.

'I feel very proud to work for M&S,' he said. 'I am a big fan of the brand and have been for years. I am really excited to be the new face of Autograph at a time when it’s looking so sharp and taking on a new trend direction.'Share

As well as modelling the new designs, Oliver was also keen to suggest how the pieces should be worn: 'I enjoyed sharing my thoughts on the new styles and also talking through how I would wear the items.'

Oliver started his career in the fashion industry when he was scouted by Select Model Management. Referred to as 'the next Leonardo DiCaprio' he secured his debut campaign when he was just 17 years old for American powerhouse Calvin Klein fronting their iconic advertising.

He has gone on to work with the biggest names in the fashion world, including Dolce & Gabbana, Versace, Missoni, Vivienne Westwood, Acne and Fillipa-K.

'I’ve always loved fashion right from when I was a boy, but my passion really developed when I was scouted by Select Model Management,' he said.

'It was amazing to be in the Calvin Klein campaign, it was one of my first jobs and I got to meet Calvin himself. My Dad flew out to New York especially to see the billboards.'

Regularly heralded in GQ's best-dressed men poll, Oliver has also been called the ‘Model with the Midas Touch’ as brands like Orlebar Brown, Superdry and M&S swimwear have seen a direct increase in sales when he has been featured as 'their face'.

Revealing how he always looks so effortlessly on-trend, Oliver said: 'The secret to dressing well is to dress for the occasion, and to understand your body shape so that the clothes fit perfectly.

'You can have the most simple outfit that doesn't cost much, but if it fits perfectly it will look great.'

He added that he hones his supermodel body by doing 'chin ups, push ups and lots of cardio'.

Key pieces from the new M&S Autograph Menswear autumn/winter 2015 line include a pale grey coat (£99), shirt (£35) smart jeans (£35) and a belt (£29.50)

Oliver said the range is perfect for men who like 'trend-led' styles, pictured in jumper (£55), shirt (£39.50) and trousers (£45)

Looking good comes easily to Oliver thanks to his defined cheekbones, piercing brown eyes and chiseled jaw. He said he can be up and out the door in '30 minutes' and his go-to outfit is: 'A pair of tailored navy chinos with a crisp white trainer, a linen blend t-shirt and a midnight navy, suede bomber jacket.'

However, before he mastered his on-point style, Oliver admits he suffered a few wardrobe setbacks.

'I think it's important to know what suits you, but I tend to try out a few little different bits to mix it up,' he said. 'I've worn a few bold shirts that I look back on now and think, "Why did I wear that?"'

If he's unsure about a certain look he'll turn to girlfriend Pixie, 24, for reassurance: 'We ask for each other’s opinions, as we value them and know we will get the truth.

'We both love fashion so we usually make a day of shopping - hitting the shops and then grabbing some food. We love Browns on South Molton Street and of course the big flagship M&S store at Marble Arch.'

As a seasoned Marks & Spencer shopper Oliver usually buys 'the men’s cashmere jumpers and the leather holdalls, and I am also a big fan of the suits as there are so many styles to choose from. This season the white soled brogues are also great!'

And he added: 'Yes, I do own a range of M&S pants.'

Come autumn Oliver can't wait to get his hands on the new line: 'I will definitely be wearing it, and I can imagine lots of my friends will love the styles too.

'Ultimately, I would say it is for men who are looking for trend led styles, and who want luxury fabrics and detail on their clothes. They have been designed in a way that is easy to wear day to night, which is perfect for my busy schedule.'

The collection is modern and contemporary with key styles including a bomber jacket with leather sleeves, geometric print knitwear and textured crew neck jumpers, as well as a selection of sports luxe trainers.

All styles will be available in over 80 UK stores and online from today.
